Heil Quaker ICP 1192578 TXV

The Heil Quaker ICP 1192578 TXV is a heavy-duty, genuine OEM thermostatic expansion valve engineered for R410A refrigerant systems. Specifically designed for 4 to 5-ton capacity units, this bi-flow TXV is critical for maintaining precise superheat levels across both cooling cycles and heat pump heating modes. By modulating refrigerant flow based on evaporator load, the 1192578 prevents liquid slugging, ensuring long-term compressor protection and optimal thermal exchange. This ICP replacement part is verified for use in high-efficiency residential and light commercial split systems, providing the mechanical reliability required by service technicians for a permanent fix over universal alternatives.

Key Benefits for Contractors

• Optimized Efficiency: Maintains precise refrigerant metering to maximize SEER ratings and heat transfer efficiency.
• Bi-Flow Capability: Engineered for seamless operation in both heat pump and straight-cool applications.
• OEM Fitment: Eliminates the need for field modifications, ensuring direct drop-in replacement for ICP, Heil, and Tempstar 4-5 ton coils.
• System Longevity: High-grade internal components resist debris fouling and ensure stable superheat control under variable ambient conditions.

Common Questions

Is the 1192578 TXV compatible with older R22 systems?
No, this valve is specifically calibrated for R410A systems. Using this with R22 will result in incorrect pressure drops and potential compressor failure.

Does this TXV kit include the sensing bulb and mounting hardware?
Yes, this ICP 1192578 TXV kit includes the valve body and the thermal sensing bulb necessary for proper suction line temperature monitoring.

Can I use this on a 3-ton evaporator coil?
This valve is sized for 4 to 5-ton applications. Installing it on a 3-ton system may cause hunting and improper evaporator flooding; always match the tonnage to your specific air handler or cased coil technical plate.
